LingQ streak functionality broken

The latest issue I’ve been having with LingQ in the last few days is streak-lost events that I have to buy my way out of with coins, when I’ve absolutely definitely maintained my streak - is anyone else experiencing this issue?

I also have an issue that on finishing a lesson and choosing the ‘next lesson’ option, the next lesson that is presented is already on its last page. This happens lesson after lesson. I’m really struggling to get any worthwhile use out of LingQ at the moment, even though I dropped back to using just the most basic functionality several months ago as the more sophisticated features, like importing videos, were too unreliable.

if it goes into a lesson on the last page just use the slider and go back to page 1… I have noticed it will go to the end of lessons I have already done before and am redoing, I have never had it open to the last page of a lesson in a playlist I have never seen before. Which behavior are you describing?
